lle it .known that l, FREDERICK lo. (InosvoLo, a citizen of the Unitedbtates, and

resident of Eau Claire, in the county of Eau Claire and Sta-te ofNisconsin, have invented new and useful improvements 1n SewenlipeCleaners, of which the follpwing is a description, reference being hadto the accompanyingdrawings, which are a part oi' this specihcaticn.

improvements in .minimum effort. n

v A further object-,of the invention 1s tol provide a sewer pipe cleanerwhich is of simple construction, 1s strong and durable `and is welladapted Jfor the purpose described.

-VViththe above and other objects ln'vlew,

the invention consists of the improved sewer pipe cleaner and its partsand combinations as set forth in the claims, and all equivalentsthereof. y

ln the accompanying drawing in which the same reference charactersindicate the same parts in all of the views: Figure l is a side View of.the limproved sewer pipe cleaner; one of the revoluble members be ing'insection; and Fig. 2 is a sectional view thereof taken on line 2-2 ofFig. l.

Referring to the drawing the numeral 5 indicates a cleaningv rod towhich the imfproved sewer pipe cleaner 6 is connected by bolts 7. Thesewer pipe cleaner comprises the attaching stem. 8 having a rearperforated llat rod connecting portion v9 and a stud shaft 10 extendingfrom its forward rounded end 8 upon which a 'trunnion block ll is'swiveled The trunnions 12 ci' the block l project from diametricallyopposite sides ,of the block and have cleaner members 13 journaledthereon which are approximately of lhemi-spherical shape with their latfaces le toward each other. lThe mem- .greater than the thickness of theforward rounded end portion 8 of the stem to permit free rotation of themembers. The members 13 are so positioned with relation to each other asto form a spherical end which is adapted to be forced through the pipeto be cleaned and which will in advancing revolve on the stud shaft atthe same time the spherical members are revolving on their trunnions.`While the parts are thus revolving the peripheral edges l5 oit' themembers 13 will out or Work through any obstruction inthe pipe andseparate it into small parts which may be easily flushed out oil thepipe.

F rom the foregoing description it will be seen that it is onlynecessary to attach the cleaner to a rod and then force it back andforth through the obstructed pipe and the revoluble end will easilydisintegrate the ob-l struction and clean the pipe..

What claim as my invention is:

l. A sewer pipe cleaner, comprising a stem, a revoluble/blcclr swiveledon one end of the stem, and revolnble cleaner members jcurnaled on theblock.

2. A sewer pipe cleaner, comprising 'a stem, a revoluble block swiveledon one end of the stem, and revolnble cleaner members journaled onopposite sides of the revoluble block.

3, A sewer pipe cleaner, comprising a stem, a revoluble block swiveledon one" end of the stem, and revoluble cleaner members journaled onopposite sides of the revoluble block, said cleaner members being ofapproximately hemispherical i'orm and being journaled on the block toform approximately a spherical eno. to the stem.

4f. A sewer pipe cleaner, comprising `a stem, a revoluble block swiveledon one end of the stem and provided with diametrically oppositelypositioned trunnions, and hemispherical cleaner members journaled on thetrunnions and having their iiat faces extendbeing positioned to formapproximately a spherical end to the stem.

In testimony whereof, l ailix my signature, in presence of twoWitnesses.
